      (on/off)   Help   NOTE: mouseover dotted underlined text for definition

Fxus62 kilm 191316 afdilm area forecast discussion national weather service wilmington nc 916 am edt Mon aug 19 2019 Synopsis A stationary front will transition into a trof of low pressure across the central carolinas and will persist thru late this week. Weak high pressure will affect the area thru the midweek period. A cold front will drop down from the north and stall across the area Fri thru next weekend. Update No significant changes to going forecast this morning. Drier air aloft will limit the areal extent of convection this afternoon, and it should be confined to areas along and inland of the sea breeze. Bermuda high will be the main synoptic feature, with temps reaching the upper 80s beaches to low 90s inland. Near term through Tuesday The fa will remain trapped between the 2 synoptic upper highs, within weak upper troffing. The upper trof axis will remain west of the ilm CWA and as a result will be affecting moreso by the flow around the bermuda high. Today models feature some drying aloft with pws having dropped below 2 inches and could further lower to around 1.70 inches. Still though, plenty of avbl moisture for convection to develop. The sea breeze and the stalled front, which will transition into a sfc trof across the central carolinas, will provide the necessary force ie. Vertical motions, to initiate convection both days. The days insolation will provide plenty of instability both days to fuel thunderstorms. Pops will run 20 to 40 today and 30-40 tue... Lowest along the immediate coast especially in the wake of the inland progressing sea breeze during both days. MAX temps will run slightly above normal today and near normal tue. The low to mid 70s dewpoints today will combine with afternoon temps in the 90 to 95 range, and produce heat indices at 100-103 degrees, just below the 105 threshold for a heat advisory. Tonights lows will run above the norm. Short term Tuesday night through Wednesday night Weak 5h cutoff develops in the break in mid-level ridge over the southeast early tue. This feature is slow to move northeast, with deep southerly flow helping to spread moisture over the eastern carolinas. As the low drifts east-northeast, it will send an occasional shortwave across the area. The enhancement of upward motion ahead of each wave coupled with diurnal instability and deep moisture will produce a convectively active period. The sea breeze and lingering convective boundaries will also act as potential triggers for daily convection. Presence of forcing outside of diurnal heating does suggest activity may continue into the overnight periods, however this will depend on timing. Passage of any shortwave will be followed by a period of decreased or even no activity before the post wave subsidence moves off and the environment becomes more favorable. Highs will be near to slightly above climo each afternoon with lows running above climo.

Long term Thursday through Sunday Unsettled conditions will continue through the start of next week with weak mid-level troughing and deep moisture lingering over the southeast. Piedmont trough and sea breeze will act as triggers while weakly divergent flow aloft aids upward motion. -scattered showers and thunderstorms each afternoon and evening. At this point severe weather does not appear to be a concern. -high temperatures near climo with low temperatures above climo. Aviation 13z Monday through Friday After ifr stratus dissipates in the next hour or two at flo, expect vfr conditions to dominate through the remainder of the valid taf period. A lingering surface trough inland and sea breeze nearer the coast may spawn isolated storms this afternoon. Coverage should be limited so this is accounted for in the terminals with vcts. Extended... MainlyVFR each day. Exceptions... Brief MVFR ifr from tstorms each aftn thru early evening... And MVFR ifr from early morning fog and or low stratus each day mainly for the inland terminals. Marine Today thru tue: flow around bermuda high will dominate the ssw-sw winds this period. The sfc pg will remain semi-tightened supporting wind speeds of 10 to occasionally 15 kt. The hier end of this range more likely will occur during the afternoon and early evening, within 10 nm, of both days due to the development of the sea breeze and its push inland. Significant seas will hold around 3 ft thruout the period with wind waves at 3 to 5 second periods dominating the aftn thru mid-evening and the 8 to 9 second period SE swell dominating at all other times. Tue night thru fri: southwest flow will continue through Fri with bermuda high sitting offshore. Changes to the gradient, as the piedmont trough strengthens and then weakens, will lead to southwest flow around 10 kt each morning increasing to a solid 15 kt each afternoon and evening before dropping closer to 10 kt overnight. Seas follow a similar to trend to winds wed, building to around 3 ft in the afternoon before dropping closer to 2 ft overnight. Southerly wind wave at 4 to 5 seconds will be dominant early in the period, but a secondary south to southeast swell around 9 seconds will help increase seas Thu and Fri to 3 to 4 ft.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
